to_2d_components
Description:
public void to_2d_components (out float out_skew_x, out float out_skew_y, out float out_scale_x, out float out_scale_y, out float out_angle, out float out_dx, out float out_dy)
Converts a `GskTransform` to 2D transformation factors.
To recreate an equivalent transform from the factors returned by this function, use
gsk_transform_skew ( gsk_transform_scale ( gsk_transform_rotate ( gsk_transform_translate (NULL, &GRAPHENE_POINT_T (dx, dy)), angle), scale_x, scale_y), skew_x, skew_y)
this must be a 2D transformation. If you are not sure, use
get_category >= gsk_transform_category_2d
to check.
Parameters:
| this |
a `GskTransform` |
| out_skew_x |
return location for the skew factor in the x direction |
| out_skew_y |
return location for the skew factor in the y direction |
| out_scale_x |
return location for the scale factor in the x direction |
| out_scale_y |
return location for the scale factor in the y direction |
| out_angle |
return location for the rotation angle |
| out_dx |
return location for the translation in the x direction |
| out_dy |
return location for the translation in the y direction |
